Table of contents

    CP Voltage:

    The connection signal between the charger and the electric car via the CP line of the charging cable is faulty. The charger is in error (status LED red) and or the on-board computer of the electric vehicle displays an error message.

    • De-energize the charger (fuse OFF) and check the charging plug and the charging socket for foreign objects or obvious damage. Remove all foreign objects; if there is a defect, take the device out of operation.
    • If no problem is found after the check, plug the charging cable in again to determine whether the fault was caused by a poor contact. Repeat this procedure.
    Type 2 plug - CP single conductor

    SPD overvoltage protection error:

    The overvoltage protection in the electric car is abnormal.

    • Restart the charger (fuse OFF / ON) and wait 2 -3 minutes until the charger is fully functional again. Then plug the electric car into the charger and start the charging process.

    Residual current:

    The fault current of the charging system (charger + electric car) exceeds the safety range.

    • Restart the charger (fuse OFF / ON) and wait 2 - 3 minutes until the charger is fully functional again. Then plug the electric car into the charger and start the charging process.

    Shooter error:

    The Charger's output contactor signal is abnormal.

    • Restart the charger (fuse OFF / ON) and wait 2 -3 minutes until the charger is fully functional again. Then plug the electric car into the charger and start the charging process.

    Phase error:

    The AC input voltage of the EV charger is out of phase.

    • Check the correct AC phase input from the charger.
    • Restart the charger (fuse OFF / ON) and wait 2 -3 minutes until the charger is fully functional again. Then plug the electric car into the charger and start the charging process.

    Neutral conductor error:

    The L / N conductors of the AC connection are reversed.

    • Check the correct installation of the L / N conductors.
    • Restart the charger (fuse OFF / ON) and wait 2 - 3 minutes until the charger is fully functional again. Then plug the electric car into the charger and start the charging process.

    PE grounding fault:

    The AC input of the charger is not correctly earthed.

    • Check the earthing status of the Charger's AC input
    • Restart the charger (fuse OFF / ON) and wait 2 -3 minutes until the charger is fully functional again. Then plug the electric car into the charger and start the charging process.

    Input overvoltage error / undervoltage error:

    The input voltage of the mains exceeds the operating voltage range of the EV charger.

    • Restart the charger (fuse OFF / ON) and wait 2 - 3 minutes until the charger is fully functional again. Then plug the electric car into the charger and start the charging process.
    • Check whether the input voltage of the charger is within the normal operating range.

    Residual current circuit breaker output:

    The signal from the residual current circuit breaker of the electric car is abnormal.

    • Restart the charger (fuse OFF / ON) and wait 2 -3 minutes until the charger is fully functional again. Then plug the electric car into the charger and start the charging process.

    Output overcurrent fault:

    The actual charging current of the EV charger exceeds the maximum permissible charging current set by the user.

    • Restart the charger (fuse OFF / ON) and wait 2 -3 minutes until the charger is fully functional again. Then plug the electric car into the charger and start the charging process.
    • Check whether the charge controller of the electric car is working properly.

    Frequency deviation:

    The input voltage of the mains exceeds the operating frequency range of the Charger.

    • Check whether the input voltage frequency of the Charger is within the normal frequency range.
    • Restart the charger (fuse OFF / ON) and wait 2 - 3 minutes until the charger is fully functional again. Then plug the electric car into the charger and start the charging process.

    Access control error:

    The side cover of the charger is open (AC installation area).

    • Check whether the side cover to the AC installation area is closed and firmly screwed on.
    • Close the side cover.

    Overtemperature error in the charger:

    The internal temperature of the charger exceeds the permissible operating temperature.

    • Check whether the ambient temperature of the charger is within the relevant operating temperature range (-30 °C to +50 °C). For example, excess temperature due to direct sunlight.
    • unplug the charging cable and wait about 10 minutes until the device has cooled down naturally. Once you have ensured that the temperature has dropped, restart the charging process.

    Overtemperature error on the charging plug:

    The temperature at the charging cable plug is monitored. If the temperature at the charging plug exceeds the safety temperature, the charging process is aborted.

    • Check whether the ambient temperature of the charger is within the relevant operating temperature range (-30 °C to +50 °C). For example, excess temperature due to direct sunlight.
    • Unplug the charging cable and wait about 10 minutes until the device has cooled down naturally. Once you have ensured that the temperature has dropped, restart the charging process.
    • Check the charging plug of the charging cable (or charging socket of the charger) for unusual conditions such as deformation and discoloration. If you notice unusual conditions such as deformation and discoloration, take the device out of operation.

    Moisture penetration:

    The humidity level inside the charger exceeds the safe range.

    • Interrupt the power supply to the charger immediately and take the device out of operation.

    RFID reader error:

    The RFID reader is abnormal.

    • Restart the charger (fuse OFF / ON) and wait 2 -3 minutes until the charger is fully functional again. Then plug the electric car into the charger and start the charging process.
    • If the error persists, the charger must be replaced.

    Internal counter communication error:

    The internal communication in the charger is abnormal.

    • Restart the charger (fuse OFF / ON) and wait 2 -3 minutes until the charger is fully functional again. Then plug the electric car into the charger and start the charging process.
    • If the error persists, the charger must be replaced.

    External counter communication error:

    Faulty communication between the Charger and the external electricity meter (optional accessory for load management).

    • Check the RS485 communication line between the Charger and the external electricity meter.
    • Check the operating status of the external electricity meter.
    • Restart the Charger (fuse OFF / ON) and wait 2 -3 minutes until the Charger is fully functional again. Then plug the electric car into the charger and start the charging process.

    Control box error:

    The behavior of the external control box (optional accessory for power throttling by the grid operator) is abnormal.

    • Check the RS485 communication line between the Charger and the external control box.
    • Check the operating status of the control box.
